Why does PCB to blinky LED take so long? 🧑🏼‍🏭

#pcb #board #bringup
After getting my PCBs from PCBWay https://www.pcbway.com/, the next obvious step was to get it soldered and flash in a simple blinky LED. But I was surprised to realize how long that took! Then I realized that there is such a thing called the "Board Bring-Up" and it does take a long time. Hence, I share a 7-step board bring-up process while making a custom Arduino board for a LoRa-GPS tracker based on Arduino Zero microcontroller SAMD21G. We will be using a J-Link EDU Mini to upload the bootloader and then test out the simplest Blinky LED along with the GPS, LoRa, and E-Ink subsystems.
